Sudoku Variants Series (431) - Split Pea Lines
(Published on 4. July 2025, 08:00 by Richard)
I will see how long it takes before I am running out of ideas.
Split Pea Lines
Inspiration for this type comes from Scojo and SamuPiano.
Solve online in Sudokupad.
Apply classic sudoku rules.
The sum of the digits on a line between two circles is equal to a concatenation of the digits in the circles, in some order. For example, 3-346-1 could be a valid split pea line, since 3+4+6=13, which is a concatenation of 3 and 1. Digits may be repeated on a line and/or in the corresponding circles.
Solution code: Column 1.

Thank you for this excellent puzzle! I am very happy to see split peas make it onto SVS :)
Some very cool geometric tricks in this one.

I have no reason NOT to include it in SVS. It's distinguishing enough from all variants I did before... Unique, so to say.
I wonder what the first one of this type is in the portal, and if there is a 'pure' one published earlier. I would love to see a puzzle of this type without other constraints too. It seems it appears under other names too, which makes searching a bit hard.
Any suggestions on this?

Hi Richard,
The first split peas puzzle was my "Schrodinger's Split Peas", which you can find on my page. In order to find these puzzles, you can search in the rules for the word "peas", which gets most of the puzzles.
To my knowledge, this puzzle is the first pure 9x9 Split Peas puzzle. Juggler has a 6x6 called "Give Peas a Chance", but constructing a pure peas puzzle is rather difficult.
Well done on the excellent implementation! -SP

This is a lovely SPL-puzzle! Before I could start to solve it I had to do some arithmetic exercises. That was fun, but also caused me to give 3*. Thank you very much for creating and sharing another beautiful SVS-episode.

Thank you for this wonderful puzzle, Richard! I would recommend also mentioning SamuPiano who has invented the amazing Split Peas constraint.

Reply: you are right sujoyku! I always prepare the text for each episode a few days in advance, and only solved SamuPiano's puzzle yesterday evening. Forgot to add that in my introduction text. Fixed now!
